T-Mobile Free Trial Offer Includes Free Hotspot, Free Month of Data

T-Mobile is inviting customers of other carriers to test its network free for 30 days, using their existing phone and before deciding to switch. To do this, it's giving away free Coolpad Surf mobile hotspots with 30 days or 30 GB of free data (whichever comes first). Users connect their existing phone to the hotspot via W-Fi, which in turn connects to the T-Mobile network. This allows users to test T-Mobile's network without switching phones or leaving their current carrier. T-Mobile is eager to show off its improved coverage. T-Mobile has spent $30 billion in recent years to add LTE in band 71 nationwide. Band 71 is a swath of radio frequencies near 600 MHz, which is lower than other mobile phone bands. The lower frequency provides farther-reaching coverage and better service indoors.
